Mountain bike modification help needed

Were you really thinking of 24" in front and 26" at the back?Originally posted by spidey3:no lah. Bicycle is all RWD. Not appropriate to have smaller back wheel. Difficult to drift.
Like that also can?

I was considering 24" back and front. I was just humoring ditzyOriginally posted by Wanda:Were you really thinking of 24" in front and 26" at the back?

You were saying you have a bike, I assume also 26". So how tall are you if I may ask? Do you have problem with the height of the bike? -
This is good enough liao

It not about the wheels mah...it's about the bike frame size. Like someone mentioned, gotta choose the bike with sufficient standover height, i.e. at least 1" space between the top tube and the groin area.Originally posted by spidey3:I was considering 24" back and front. I was just humoring ditzy

I'm less than 1.6m, and my bike frame is about size 15 (not very easy to find though)....yes, with 26" wheels, as per normal mtn bike. -
Really not advisable. Have to change pratically everything. Resign to fate. Mine also slightly higher.

Bottom line is, you cannot simply change the wheel sizes. as mentioned earlier, most frames are built specifically for a certain wheelsize only (there are some which have adjustable brake bosses, but that's a different story)
it appears that your friend bought a frame that is too large for her; which is pretty unethical of the salesperson, whom should have known better than to recommend the particular frame to her.
I'd advise that you get your friend to change to a smaller frame ( typically, most ladies will be comfortable with a 14"-16" frame.
PM me if you need assistance with that. -
aiya behind change to smaller diameter one,than remove the brake can liao
i mean behind that one -
Well from what I know, you need not have to change the cassette(gears) because if changing the size meaning changing the diameter of the rim and length of the spokes. Not sure about the hub which holding the cassette though. I ain't a wheelbuilder. Contact reputable bikeshop for more professional assistance.Originally posted by spidey3:Yes, I think they are V-brakes. And that was what i think also. The brakes has to be change to accomodate the small diameter of the wheels. The original breaks pads will not reach the correct position if using 24" wheels.
What about the gears on the back wheel. Do you think it need to be change if we change to a 24" wheel?
JasonC mentioned about changing of frames and it seems like good idea.
Not that I have anything against icYwATeR but removing the brake isn't a good solution and its dangerous especially on the streets of Singapore.

yes I do feel the salesperson had not given a good service. Though he had not pressure her into the sales I do think he could have done more in his giving us an expert advice.Originally posted by JasonC:Bottom line is, you cannot simply change the wheel sizes. as mentioned earlier, most frames are built specifically for a certain wheelsize only (there are some which have adjustable brake bosses, but that's a different story)

The bike she bought had a frame of 17". The top tube is slightly slanted towards the seat (and not totally horizontal) giving it a bit of a woman bike look. Still when she stands just above the top tube, she has to tip toe. There is no 1" clarence as mention by Wanda.
She went for it because she is pretty sure height will not be a problem for her. She has been riding bikes since a young age and has said that she even has no problem riding adult bike when she was in primary school. But that is on even tarmac. I just think she will have problem on a dirt or hill track - which we hope to try out.
We bought the bike but it is not delivered yet. So I think there is still a possibility to change it. But the thing is there is not many other option. -
changing frame. I don't know. Form what I see - I think the frame is the most expensive component for this bike. It is a 6061 aluminium frame. Very light but solidly built.Originally posted by mase101:Well from what I know, you need not have to change the cassette(gears) because if changing the size meaning changing the diameter of the rim and length of the spokes.

Removing the brakes It is like chopping of the head to cure a headache.
About the hub to hold the cassette - this component (hub) you are saying is specific to the wheels. So that the hub of one wheels will not fit another type of wheel. -
I think it's better to change. But my friend she's riding my bike and coping well though.

Thanks for the help.
You do seem to have a bit of knowledge in this subject on mountan bike.
Can a road bike use a moutain bike type tyres? -

behind one disk brake loh -
Better change to a smaller bike, since you've not taken delivery yet, esp. if she has to tip toe - it's very tiring to have to tip toe whenever you stop at the traffic lights, etc, and a bit risky unless she's a very confident rider.
I could cope with a 17" bike (before I had my own bike), but a bigger frame means heavier weight and a less comfortable feel in manouvering (sp?). So go for a smaller frame that suits the lady's height. -

wheels 26" diameter too high for friendOriginally posted by spidey3:my friend is not very tall and she has to tip toe. Can manage but I am afraid will have problem on uneven terrain.
I notice if she tries a bike with 24" wheel her foot can touch the ground flat. I think reducing the wheel to 24" will make the sit height down by atleat 2".
wheels changed to 24" diameter from 26" will only down sit height by 1" not 2". when bike stationery on even road can rest on one side before moving off again. higher bike when u make a turn at higher speed can feel a difference. but since its mountain bike you may want to choose one that you are comfortable with - psychologically, before you use it on rough terrains.
if possible to change to another one with different specification then work on it lor.
i dun know bicycle got so many theories one my yellow cheap old ah pek bucycle rotting and collecting dust outside my flat one day must sell to rag-and-bone man dun know he want or not
-
the reason I ask is because when we were shopping around - we actually found this road bike which she like very much. It has 17" frame and come with either a 18" or 22" wheels. Very narrow wheels - completely road bike. Height just nice - 18" for her and 22" for me.Originally posted by icYwATeR:Road bike use mountain bike tyres
can meh?
We thought about what we want to use the bike for. She was more for going riding of the tar road. But I was more into going riding off road. So we kind of went for a mountain bike (the 26" model) instead which is more all terrain. But I forgot to ask the salesman, whether it is possible to get the road bike but change to nobbly tyres. -
Technically, no.Originally posted by spidey3:Hi JasonC,

Can a road bike use a moutain bike type tyres?
however there is a breed of bikes known generally as a "Cyclocross' - essentially a frame with a geometry more geared towards a road frame, but with knobblies (MTB Tires),
also, there's a new hype going around now, the 29er, or 29" MTB
these are generally MTBs with 29" wheelsets, which are pretty close in size to those of a roadie (roughly 700c).
if you intend to use your mtb mostly for tarmac, then a good way to go (without breaking the bank) is to switch over to slicks. -
This cyclocross - are they sometimes call hybrid bikes?Originally posted by JasonC:Technically, no.

Btw, Buy bmx la.. bmx cruiser comes in 24", more sporty although single gearing..
"drifting" on a bike is pressing the back brake hard and ''ski'' -
Like someone said, get disc brakes for the rear, but first you need disc hubs and the calipers, the levers should do.
Then lace 24 in rims to the hub. -
what frame is it?Originally posted by spidey3:changing frame. I don't know. Form what I see - I think the frame is the most expensive component for this bike. It is a 6061 aluminium frame. Very light but solidly built.

About the hub to hold the cassette - this component (hub) you are saying is specific to the wheels. So that the hub of one wheels will not fit another type of wheel.
Maybe find someone who owns the same model then swap? -
roadie with knobby tyres?Originally posted by spidey3:the reason I ask is because when we were shopping around - we actually found this road bike which she like very much.

Gonna be a jarring ride.
and somemore, the gearing will be another problem. -

The one MTB we bought is the FormulaXT (4th row - first picture)
The road bike she liked is the Crossbreed X5 (1st row - third picture)
